A workflow for fuzz testing software dependencies across open-source projects with software-bill-of-materials tools, which list a project’s components.

It helps sample projects, run dependency-graph checks with several tools, compare findings, and file grouped GitHub issues.

It automates broad comparisons and highlights unusual or suspicious results that may need investigation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.00569
Opus 5	$0.00028	$0.00284
Sonnet 5	$0.00011	$0.00114
Haiku 4.5	$0.00006	$0.00057

Security

Grade A, and why

diet-fuzz scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/diet-fuzz — Batch Diet Fuzz Testing

Full specification: See .github/prompts/diet-fuzz.prompt.md for the complete execution pipeline, project selection algorithm, and issue filing format.

Quick Reference

Full run: /diet-fuzz all — 5 projects × 4 languages × 3 SBOM tools
Targeted: /diet-fuzz go,typescript --count 10 — 10 projects × 2 languages
Single tool: /diet-fuzz python --tool syft --count 3
Curated: /diet-fuzz all --projects-file projects.txt
High parallel: /diet-fuzz all --max-parallel 8

Pipeline

Pull origin/main & rebuild uzomuzo-diet
Select projects (stratified sampling or projects-file)
Pre-filter (clone + SBOM, skip empty dependency graphs)
Run uzomuzo-diet per project × tool
Detect anomalies (IBNC, EOL-ZERO-SCORE, HIGH-SCORE-BUT-HARD)
Compare with previous runs (auto-diff)
Auto-file/update GitHub issues (grouped by root cause)
Append new findings to uzomuzo-diet-findings.md
Display cross-language summary table

Key Points

Stratified sampling: Projects chosen across popularity tiers (stars) and time periods for parser pattern diversity
All SBOM tools by default: trivy, syft, cdxgen — cross-tool comparison reveals tool-specific issues
Auto issue management: Creates new issues or adds evidence to existing ones, labels bug + diet-trial + lang:*
Regression detection: Compares with past runs to catch accuracy regressions
Pre-filter: Skips projects where SBOM has no dependency graph (avoids wasted diet runs)
Uses gh api (REST) for GitHub operations to avoid GraphQL rate limits

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

diet-fuzz is a skill published in the GitHub repository future-architect/uzomuzo-oss (32 stars, last pushed 3d ago), licensed Apache-2.0. It adds 56 tokens to every session and 569 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
